How to connect to Windows Internal Database(MICROSOFT##SSEE instance)

You’ll see the following error when trying to connect to a SQL Server Embedded Edition instance, aka Windows Internal Database(MICROSOFT##SSEE instance) using SQL Server Management Studio if you are directly using the server name.

Cannot connect to MachineName\MICROSOFT##SSEE.

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

To connect to the Windows Internal Database using Management Studio, specify the server name as \\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query

EDIT: On Windows Server 2012, it seems that we'll need to use \\.\pipe\MICROSOFT##WID\tsql\query. I haven't tried this as I don't have a Windows Server 2012 machine yet, but it is based on the comment below from Stephan. 

Hope this helps!


  1. Hi

    Just 4 information: On Windows Server 2012 Windows Internal Databases you have to use following server name: \\.\pipe\MICROSOFT##WID\tsql\query
    Your string doesn't work on 2012.

  2. Thank you Stepahn. I've updated my post to ad the string for Windows Server 2012.

  3. Thanks Stephan, and Faisal for updating. I used \\.\pipe\MICROSOFT##WID\tsql\query on my Server 2012 Standard installation to access the WSUS database via SQL Server Management Studio 2008 Express.
